• Puritanical (Adjective) – of, relating to, or characterized by a rigid morality/ extremely or excessively strict in matters of morals and religion

Taken from Margaret Atwood’s  “There Once Was”

“Another thing. Good and Wicked. Don’t you think you should transcend those puritanical judgemental moralistic epithets? I mean, so much of that is conditioning, isn’t it?“

Atwood used the word puritanical to show the speaker’s point of view at how the idea of “good and wicked” are used in stories, expressing her disapproval that such things were just based on moral principles that was reinforced by old beliefs and that it’s time to move on to that cliche expression.
